cloud king Populate Clouds special power seams broken are standing on cloud terrain and it is greyed out

i am close (one tile) to sky forests and a natural spawning cloud village and a cloud hamlet

but when i moved to the to upgrade the hamlet and go back i somehow can but not upgrade ?

seams very inconsistent

nonearby1req means that there is a 3x3 area wherein the ritual cannot be cast, centered on the selected terrain.

This means you need at least one intervening non-cloud hamlet square in a cardinal direction.

Example:
C = ritual castable X = Ritual not castable T = Limiter Terrain (Cloud Hamlets in this case)

C C C C C
C X X X C
C X T X C
C X X X C
C C C C C

The limiter is completely consistent, but this is a simplified example, as you can wind up with a veritable minefield of limiter terrain if you don't plan things out. Moreover, you need to plan for multiple terrain limiters, as the hamlet upgrade also have limiters, some of which are more restrictive.

you should probably add this info to the tooltips because there just says can only be cast in a cloud

which make it seams like you can cast it everywhere (in a cloud) it wold make it easier for beginners like me

also the Form Cloud Castle spawn Cloud palace

and it would be nice if there was a way to remove Sky Flowers and Sky Fungus

Automatic tooltips can only be changed based on the restrictions of the spell. Terrain limiter tooltips are very specific. If it says cloud, it means the terrain "Cloud".

As for the ritual, that is perhaps a misnomer. Cloud Palace is the Cloud Lord's hometerr and primary citadel, while a cloud castle is a gateway to the plane of air with similar defenses and higher income. Provided I remember, I'll change the name later.
